Embodiment 1
Kitchen castoff is cooperateed with processing with domestic sludge by Jiangsu city organic matter processing center, and mixture is in anaerobism
Tank anaerobic fermentation generates biogas, grid-connected use after purification.
During kitchen rewinding, integrated kitchen receives fortune vehicle and connect discharging with discharge port 1 by pipeline.It eats after discharging
Kitchen waste is fallen into level-one feed bin 2, and level-one feed bin 2 and second level feed bin 3 are interconnected, and centre is equipped with slag trap 4.When kitchen is useless
After gurry enters level-one feed bin 2, the impurity such as bone slag, eggshell, shell gradually accumulate precipitating by gravity in kitchen castoff
To feed bin lowest part.2 bottom of level-one feed bin is equipped with slagging-off screw conveyor 7, and unlatching can be by bone slag, the egg of 2 bottom of level-one feed bin
The impurity such as shell, shell are delivered in solid slag dustbin 8, and dustbin is by staff's periodic cleaning, and cleaning is primary daily.Work as level-one
2 material of feed bin gradually increases, and kitchen castoff liquid level is more than slag trap 4, then the water in waste, oil and light solids substance flow into
Second level feed bin 3.Second level feed bin lower part is equipped with 6 discharging pumps, opens the anaerobic digestion that a large amount of materials can directly be squeezed into subsequent technique
System.3 second level feed bin, 3 top mentions oil groove 5 equipped with multiple, there is certain inclination angle, and when second level feed bin 3 reaches high liquid level, kitchen is useless
Oil reservoir inflow in gurry the top mentions in oil groove 5, then enters next step three phase separation oil extracting process by oil guide pipe 9, refines crude oil.
Second level feed bin 3 is in high liquid level operation, is emptied once by discharging pump 6 weekly.3 top seal of level-one feed bin 2 and second level feed bin,
There are openable access panels 10 to facilitate later period maintenance, and sealing can effectively avoid foul smell and leak, and prevents kitchen material from producing to air
Raw secondary pollution.After transformation, pipeline is no longer blocked for plant area, and anaerobic jar load reduces, and production capacity greatly improved.
Although the utility model has been described by way of example and in terms of the preferred embodiments, they are not for limiting the utility model
, it is any to be familiar with this those skilled in the art, in the spirit and scope for not departing from the utility model, it can make various changes or retouch from working as,
Therefore the protection scope of the utility model should be subject to what claims hereof protection scope was defined.
